ReiserFS and RAID1

[KS]

Hi there,
We are currently running RAID1 on some of our servers. We have thre ext2
filesystem. However we are considering seting up some test server to check how
much using ReiserFS would improve the speed. 

On their pages they say that their filesystem works with RAID1 , but not with
RAID5. Another thing thay say that the mirroring sync tools have the bug and
that one have to sync the mirror with the FS unmounted. Since we have / on
raid1 I don't think we could try ReiserFS.

Any comments on this.

Thanks in advance.
Chris
